Hi, after some advice please. I recently had an EV charger installed and was recommended at the time to upgrade the mains fuse to 100A. UK Power Networks have said they can do this for free, however I need to get my meter tails upgraded to 25mm before they can do so. My energy company (Tonik) initially didn't understand what I was requesting, but after a bit of to'ing-and fro'ing with their metering team have said that their 3rd party supplier can do this, but as they don't own the meter they'll need to replace it at a cost. The annoying bit is that National Grid via Tonik upgraded me to a smart meter 3 weeks ago, and now I'm been told that I need the smart meter replacing with exactly the same one. Anyone got any advice on how to proceed, and if there's another option for upgrading the tails?
